Possible PEAR_Error values
Error code Error message Reason Solution
every error code   Database specific error Check the name of the sequence. If correct, probably a bug in the sequence implementation


This function can not be called statically.

When using PEAR DB's sequence methods, we strongly advise using these methods for all procedures, including the creation of the sequences. Do not use PEAR DB's methods to access sequences that were created directly in the DBMS. See the warning on the "Intro - Sequences" page complete information.
